*The two rappers least likely to be involved in a hip hop beef are knee deep into one.

It all started back in December, when Common confirmed that a few lines from “Sweet” (Specifically: “Some ho-ass n—as … Singing all around me man, la la la … You ain’t muthaf***ing Frank Sinatra. Uh, lil b**ch”) were meant for Drake. [Watch below. The dissing referenced above is at 1:38.]

The Toronto rapper fired back a bit in concert and on Twitter, but his official response came last Friday, in a verse on Rick Ross’s “Stay Schemin.” He raps: “I just ask that when you see me, you speak up ni—a, that’s all / Don’t be ducking like you never wanted nothing”. [Watch below – Drake’s dis verse begins at 1:48.]

Then, yesterday morning, Common dropped a “Stay Schemin” remix and – ladies and gentleman, we have another rap beef.

According to the blogs, the root of their conflict is one Serena Williams, ex-girlfriend to Common and “friend” of Drake.
